The radiocarbon date was thus not valid for determining the true age of the shroud." "As part of the Shroud of Turin research project (STURP), I took 32 adhesive-tape samples from all areas of the shroud and associated textiles in 1978." "It enabled direct chemical testing on recovered linen fibers and particulates".
tests negative]." "Because the shroud and other very old linens do not give the vanillin test [i.e.The results were compared to similar tests on samples of cloth from between 3250 BC and 2000 AD whose dates are accurately known.FTIR identifies chemical bonds in a molecule by producing an infrared absorption spectrum.He co-authored reports of the findings in 1) a paper in the journal Vibrational Spectroscopy, July 2013, "Non-destructive dating of ancient flax textiles by means of vibrational spectroscopy" by Giulio Fanti, Pietro Baraldi, Roberto Basso, and Anna Tinti, Volume 67, pages 61-70; 2) a paper titled "A new cyclic-loads machine for the measurement of micro-mechanical properties of single flax fibers coming from the Turin Shroud" by Giulio Fanti and Pierandrea Malfi for the XXI AIMETA (Italian Association of Theoretical and Applied Mechanics) congress in 2013, and 3) the 2013 book "Il Mistero della Sindone" (The Mystery of the Shroud), written by Giulio Fanti and Saverio Gaeta in Italian.IMAGE FORMATION VERSUS WORK OF AN ARTIST No one knows for sure how the images were created.Ray Rogers, retired Fellow with the Los Alamos Scientific Laboratory and lead chemist with the original science team STURP (the 1978 Shroud of Turin Research Project, involving approximately 35 scientists directly examining the Shroud for five days), has shown conclusively that the sample cut from The Shroud of Turin in 1988 was taken from an area of the cloth that was re-woven during the middle ages.
Here are some excerpts: "Pyrolysis-mass-spectrometry results from the sample area coupled with microscopic and microchemical observations prove that the radiocarbon sample was not part of the original cloth of the Shroud of Turin.
In 2002, a team of experts did restoration work, such as removing the patches from 1534 and replacing the backing cloth.
One of the specialists was Swiss textile historian Mechthild Flury-Lemberg.
Dyeing was probably done intentionally on pristine replacement material to match the color of the older, sepia-colored cloth." "The dye found on the radiocarbon sample was not used in Europe before about 1291 AD and was not common until more than 100 years later." "Specifically, the color and distribution of the coating implies that repairs were made at an unknown time with foreign linen dyed to match the older original material." "The consequence of this conclusion is that the radiocarbon sample was not representative of the original cloth." "The combined evidence from chemical kinetics, analytical chemistry, cotton content, and pyrolysis-mass-spectrometry proves that the material from the radiocarbon area of the shroud is significantly different from that of the main cloth. John Jackson and Propp in 1998, which replicated the famous Fire of 1532, demonstrated that the fire added carbon isotopes to the linen. Journal of Archaeological Science, Volume 23, Issue 1, Pages 109-121. They comprise three tests; two chemical and one mechanical.
The radiocarbon sample was thus not part of the original cloth and is invalid for determining the age of the shroud." "A significant amount of charred cellulose was removed during a restoration of the shroud in 2002." "A new radiocarbon analysis should be done on the charred material retained from the 2002 restoration." 2. The chemical tests were done with Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy, examining the relationship between age and a spectral property of ancient flax textiles.
She was surprised to find a peculiar stitching pattern in the seam of one long side of the Shroud, where a three-inch wide strip of the same original fabric was sewn onto a larger segment.
